Could you please try attached patch for building Apache modules using
apxs via cmake?
I think it is needed to use add_library(... INTERFACE ...) for the Apache
modules. I confirmed quickly that the built modules work with Apache on
Ubuntu and Windows.
Also, I'd suggest to use LF rather than CRLF for newlines in
build/cmake/FindHttpd.cmake.
